WILLIAM B. HAMILTON, OF BRIENSBURG, KENTUCKY.

WAGON-BRAKE.

SPECIFICATION formingpart of Letters Patent No. 234,276, dated November 9, 1880.

Application filed May 10, 1880. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM B. HAMILTON, of Briensburg, in the county of Marshall and State of Kentucky, have invented a new and valuable Improvement in Wagon-Brakes; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure l of the drawings is a longitudinal section of a vehicle, showing my brake applied. Fig. 2 is a bottom "iew thereof, and Fig. 3 is a detail.

This invention has relation to improvements in wagon or vehicle brakes; and it consists in certain novel combinations of devices, as hereinafter fully set forth.

In the annexed drawings, the letter A designates the vehicle-bod y B B, respectively, the front and rear axles; and O is areach connecting the said axles.

D indicates strong metallic plates, pivoted by means of a bolt, a, to the reach, and extending out laterally beyond the same. To these plates are rigidly secured the brake-bars D, supported from the vehicle-body by means of the metallic rods or chains b. The bars D carry at their ends the removable shoes 0, and are connected, by means of the rods d, to the ends d of the lever E, fulcrumed on the reach near the rear axle, B. This lever straddles the reach, with its power end extending up above the same, and its branched arms 01 reach out laterally as far as the point of attachment of the rods d to the brake-bars. These rods are flexibly coupled or pivoted both to the arms d and to the brake-bars D.

F indicates afoot-lever extending up through a slot, 8, in the bottom of the body, near its front end, and fulcrumed at its lower end in the curved parallel metallic hangers e, secured to the under side of the bottom at each side of said slot. These hangers are provided at their lowest point With eyes for the reception of the fulcrum-pinor journals of the lever. The power end of lever E is connected, by means-of arod,

G, to the foot-lever F just below the bottom. The connecting-rods are secured to the brakebars near their outer ends, and the arms 01 reach out from the fulcrum of lever E on the reach as far as the point of attachment thereof to the said bars; hence when the foot-lever is thrust to the front and the power end of the lever E drawn in a corresponding direction the bars D are drawn by a vibratory motion, so as to bring the shoes by a direct movement against the rear wheels. The pressure thus obtained is peculiarly forcible, owing to the arrangement of the foot-lever at the front of the vehicle, of the branched lever near the rear end thereof, and the extension of the branches d outward in the manner described.

What I claim as new, and desire to secure by Letters Patent, is-

1. The wagon-brake consisting of the brakebars D, pivoted independently to the reach, extending out beyond the rear wheels, carrying the shoes 0, and supported by the rods 1) from the vehicle-body, the lever E, fnlcrumed on the reach near the rear axle, and having branches (1 extending out nearly to the wheels, the parallel rods d, connecting the ends of said branches, the foot-lever F, fulcrumed in hangers 6 below the wagon-body and extending upward through slotstherein, and the rod G, connecting the power end of lever E with the footlever above its fulcrum, substantially as specified.

2. The combination, with the brake-bars D, independently pivoted to the reach and suspended from the body A, of the lever E, fulcrumed on said reach near its rear end, and having the laterally-projecting branches at, the parallel connecting-rods d d, the foot-lever F, and the rod G, connecting the two levers, substantially as specified.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

WILLIAM B. HAMILTON.
